[Boatanchors] Periodic Search for Mackay Manual & parts

[Doug Hensley]

I'm not aware of any lists catering to Merchant Marine radios so asking on
these two popular lists.

Thanks to Nick England, I now have a beautiful Mackay 3007A Receiver which
looks something like the VLF model 3001 or 138 but covers the HF bands.
This late version has an added 70 kHZ IF amplifier in it which uses a Petersen
Type Z-1 FT-243 crystal cut for 1770 kHZ.

This generates two needs:  first, that crystal was missing from my set and the
closest thing I have found was a 1761.5 kHZ xtal which may allow me to de-tune
the stage a bit to get some use of it.  But, like any radio fan, I would very much
like to find an original 1770 kHZ xtal and do not want any soldered in substitute.

Secondly, I'm searching for an alignment procedure for this radio.  I have found
what I think is an adequate schematic but have found no manual yet which covers
the 3007A & its internals as many other radios did.  Unlike RCA who produced
some very good manuals for its late marine radios (such as the CRM-R6A),
Mackay would put absolutely the minimal information such as recommended
spares and base schematic in its MRU folders.

So, manual & crystal for the 3007A.  IF you can assist, please QSL.  Thanks
